I thought I'd introduce the Embedded group to Target Communication Framework (TCF).
It is used to enable embedded debugging.
There is a version of Eclipse which support TCF.
http://www.eclipse.org/tcf/http://wiki.eclipse.org/TCFCompanies involved are Intel Corporation, Wind River and Xilinx, Inc.
It was explained to me that you can eliminate GDB with Eclipse TCF for embedded debugging.
I am not familiar enough to know how TCF replaces all the capabilities of GDB.
Enjoy,
